@Cloud4DevOps... We will whitelist IP ranges in SG also naa....instead of LB

[@Cloud4DevOps]

SG we just open 443 port so not required..its just secure communication

[@srikanthreddy1365]

@@Cloud4DevOps ok.But in SG also we will choose one option naa custom IP or my IP. In that place we will whitilist naa IP

@@srikanthreddy1365 SG u dont need to touch anything , keep 443 open and use source ip for whitelisting

Thank you. Your content is always great and helpful. I have a question as we are using ALB and ALB's can have Security Groups attached so can't we whitelist CIDR ranges in there so block unwanted CIDR's? I get that we use this approach to display custom messages to the users who are trying to access from unwanted ranges. Is this correct and if you can add anymore reasons. Thanks again.

[@Cloud4DevOps]

You can restrict unwanted request at SG level and NACL level too.. Only prob there is if you are using ALB as multi tenant like hosting 200 diff customer FQDN in that case you cannot use restriction at ALB SG level itself as it will restrict all customers which we dont want to do as every customer has diff requirement , few of them want whitelisting few of them not .. This implementation make sure that we dont mix multi customer environment and yes custom message make its more useful too.. Hope that answer your query..
